(Integer Equivalent of a Character) Here is a peek ahead. In this chapter you learned about integers and the type int. C++ can also represent uppercase letters, lowercase letters and a considerable variety of special symbols. C++ uses small integers internally to represent each different character. The set of characters a computer uses and the corresponding integer representations for those characters are called that computer’s characterset You can print a character by enclosing that character in single quotes, as with
cout «; // print an uppercase A
You can print the integer equivalent of a character using static_cast as follows:
cout « static cast<int>(‘A); // print>’A’as an integer
This is called a castoperation (we formally introduce casts in Chapter 4). When the preceding statementexecutes, it prints the value 65 (on systems that use the ASCII character set). Write a programthat prints the integer equivalent of a character typed at the keyboard. Store the input in a variable oftype char.Test your

- When you perform arithmetic operations with operands of different types, such as adding an int and a float, ____________. C# chooses a unifying type for the result you must choose a unifying type for the result you must provide a cast you receive an error messagearrow_forwardLANGUAGE:JAVA Code the program that converts uppercase letters to lowercase and lowercase letters to uppercase of a word with amaximum length of 25 characters entered from the keyboard. (After the character library functions are explained)arrow_forward4. Odd-Even-inator by CodeChum Admin My friends are geeking out with this new device I invented. It checks if a number is even or odd! ? Do you want to try it out? Instructions: In the code editor, you are provided with a function that checks whether a number is even or odd. Your task is to ask the user for the number of integer, n, they want to input and then the actual n number values. For each of the number, check whether it is even or odd using the function provided for you. Make sure to print the correct, required message. Input 1. Integer n 2. N integer valuesarrow_forward
- C++ Please How do I compare four numbers and rank them from highest to lowest. For example, I ask a user to enter a grade for four students and I want them to show the student from highest to lowest and the display the person with the highest grade as well.arrow_forward[C++] Make a program that allows you to create free question exams. The user must enter the number of questions that the exam will have. The program must allow changing the name, date, time, id and the questions that are placed. The format of an exam is (example) : Name: ID: Date: 2/2/2021 AC Hour: 2:0:0 PM Questions: 1) How far away is the sun? 2) How far away is the moon? 3) How do airplanes fly?arrow_forwardCODE USING C++ We've already tried comparing 3 numbers to see the largest among all, so let's try a more complicated mission where we locate where among the 5-digit integer is the largest one. There are only 4 possible cases for this mission: if the largest digit is the first digit, print "Leftmost" if the largest digit is the third digit, print "Middle" if the largest digit is the last digit, print "Rightmost" if none of the above is correct, print "Unknown" Now, show me how far you've understood your lessons! Input A line containing a five-digit integer. 14632 Output A line containing a string. Middlearrow_forward
- Write C assignment statements for the following: a. Assign a value of 0 to a variable called between if n is less than -k or greater than +k; otherwise, assign 1. b. Assign a value of 1 to a variable called divisor if digit is a divisor of num; otherwise, assign a value of 0. c. Assign a value of 1 to a variable called lowercase if ch is a lowercase letter; otherwise, assign a value of 0.arrow_forwardQuestion 2 A number in base 2 (binary) is a number such that each of its digits is O or 1. To convert from binary to decimal (base 10), the digits starting from the right are multiplied by powers of 2 (starting at 0) and added. For example, the value in decimal of 10011 is calculated as follows: Write a program that reads from the user a 5-digit integer representing a value in binary and displays its equivalent value in decimal. Note that if the user enters an integer which digits are other than 0 or 1, the program displays a message stating that the number is invalid. Sample Run 1: Enter a 5-digit integer made of Os and 1s: 10011 10011 in decimal is 19 Sample Run 2: Enter a 5-digit integer made of Os and ls: 13001 13001 is not validarrow_forwardPlease fix code using C++this is now costing me 2 questionsarrow_forward
- CODE USING C++ There are different kinds of numbers, but among them all, the most commonly used numbers in our daily lives are those positive ones. So, I only want you to count all the positive numbers from the 4 inputted values and print out the result. Go and search for the positive ones among these four! Input A line containing four numbers (may contain decimal places) separated by a space. 2·-4·3.6·1 Output A line containing the total number of positive integers. 3arrow_forwardIn c++ you have 5 different countries, Each country contains two different integers. Example England(30, 10) in that format, how will you calculate and find the country with the smallest integers between those 5 countries and also calculate and display the total steps that country has compared to the other countries. Example…England has 50 steps.arrow_forwardQuestions: You are expected to generate a password of 8 characters. These characters can be between numbers and alphabets letters (small and larger). Arrays cannot be used in your programs. USING C++arrow_forward
